Vascular Surgery
A diabetic foot ulcer is an open wound that can become infected and may be difficult to heal, particularly when diabetes-related nerve damage or reduced blood flow is present. Early assessment helps identify infection, pressure, circulation problems and other factors affecting healing.

Treatment may involve wound care, infection management, pressure relief and evaluation of blood flow. Some ulcers require specialist procedures or surgery.
A diabetic foot ulcer is an open sore or wound on the foot that occurs in a person with diabetes. Nerve damage can reduce pain sensation, while poor circulation can impair healing. Infection, pressure, repeated injury and uncontrolled blood glucose can make a wound harder to heal. Prompt medical assessment is important because severe infection or tissue damage can threaten the foot.
Diabetic foot ulcers commonly develop when diabetes affects sensation, circulation or the ability of the foot to withstand repeated pressure. A small blister, cut, callus or pressure area may go unnoticed when protective sensation is reduced.
A wound can become infected and, in more advanced cases, infection may involve deeper tissues or bone. Reduced blood flow can further delay healing. For this reason, treatment should address not only the wound but also the factors that caused or are preventing healing.
People with diabetes may have reduced sensation and may not notice a wound until it has become larger or infected.
Reduced sensation can make cuts, burns, blisters and pressure injuries difficult to notice.
Poor circulation can reduce oxygen and nutrient delivery needed for tissue repair.
Poorly controlled diabetes can contribute to nerve, vascular and immune problems that affect healing.
Increased mechanical pressure on the feet may contribute to skin breakdown and delayed healing.
The risk of nerve and vascular complications can increase with the duration of diabetes.
High blood pressure, high cholesterol, smoking and other vascular risk factors can affect foot health.
A diabetic foot problem can involve an ulcer, neuropathy, infection or circulation changes. Symptoms vary, and reduced sensation can make a serious wound surprisingly painless.
A cut, blister or wound that does not heal normally.
Drainage from a wound may indicate infection and needs assessment.
Increasing redness, warmth or swelling can occur with inflammation or infection.
Neuropathy may cause numbness, burning, tingling or reduced pain sensation.
Discoloration, dark tissue or changes around a wound can be warning signs.
Calluses, repeated pressure and deformities may contribute to ulcer formation.
Evaluation looks beyond the visible wound. A clinician may assess the ulcer's size and depth, surrounding skin, infection, sensation, foot pressure, pulses and blood flow. Additional tests are selected according to the clinical findings.
The wound is assessed for size, depth, drainage, tissue condition and surrounding inflammation.
Sensation may be assessed to identify diabetic neuropathy and reduced protective sensation.
When poor blood flow is suspected, vascular examination and appropriate vascular testing may be needed.
Blood tests may be used when infection, inflammation or other systemic concerns need evaluation.
X-ray and, when indicated, MRI or other imaging can help evaluate deeper tissue or bone involvement.
The appropriate investigations depend on the wound, symptoms and clinical examination. Not every patient requires every test.
Diabetic foot ulcer treatment depends on wound severity, infection, tissue involvement, pressure on the foot, blood flow, neuropathy and overall health. Treatment often requires more than one approach.
Appropriate wound cleaning, dressings and regular assessment help create conditions that support healing.
Dead, damaged or infected tissue may be removed when clinically necessary to support wound healing and control infection.
Reducing repeated pressure on the ulcer is an important part of care for many diabetic foot wounds.
When a bacterial infection is diagnosed, treatment may include appropriate antibiotics and wound care based on the clinical situation.
If poor circulation is contributing to non-healing, vascular evaluation may identify whether revascularization such as angioplasty or bypass is appropriate.
Selected patients may require procedures such as debridement, reconstruction, skin grafting or, when tissue cannot be preserved, amputation.
A diabetic foot ulcer may persist if infection, pressure, neuropathy or poor circulation is not addressed. A specialist assessment can help determine the priorities for care.
Removal of dead or infected tissue may be required when wound care alone is not sufficient.
Angioplasty, bypass or another vascular procedure may be considered when inadequate blood flow is preventing healing.
In selected wounds, a skin graft may be considered after the wound bed is suitable for closure.
Selected deformities or structural problems may require reconstructive treatment to improve function or reduce repeated pressure.
Deeper infection may require surgical removal of infected tissue or other specialist treatment.
Amputation is generally considered only when severe infection, tissue death or non-salvageable damage makes preservation of the affected part unsafe or impossible.
Surgery is not automatically required for every diabetic foot ulcer. The goal is to control infection, preserve viable tissue, support healing and protect function whenever possible.
Healing time varies significantly. The original page states that an ulcer may take 1–3 months with treatment, but this should not be treated as a fixed timeline for every patient.
Healing can be affected by ulcer size and depth, infection, blood flow, neuropathy, pressure, blood glucose control, nutrition and adherence to the treatment plan.
A wound that is improving should be monitored regularly. If an ulcer becomes larger, develops new drainage, changes color or develops increasing redness or swelling, contact a healthcare professional.

View Vascular SurgeryEarly warning signs can include a persistent open wound, redness, swelling, warmth, drainage, skin changes or a blister that is not healing normally. Reduced sensation may make the wound painless.
Regular foot inspection, good foot hygiene, appropriate footwear, diabetes management and regular foot checks can help reduce the risk. Prompt attention to minor injuries is also important.
Treatment depends on the wound and its underlying causes. Care may include wound dressings, debridement, pressure relief, infection treatment, vascular evaluation and selected surgical procedures.
Seek medical assessment for a persistent wound, increasing redness or swelling, drainage, foul odor, fever, skin discoloration or any wound that is not healing normally.
Severe infection, extensive tissue damage or non-salvageable tissue can sometimes lead to amputation. Early treatment aims to control infection, support healing and preserve viable tissue whenever possible.
Healing time varies according to wound size and depth, infection, circulation, neuropathy, pressure, diabetes control and treatment. The original page mentions 1–3 months, but this should not be considered a guaranteed timeline for every patient.
No. Many ulcers are managed with wound care, pressure relief and treatment of infection or other underlying problems. Surgery is considered when clinically necessary.
Yes. Reduced blood flow can impair tissue oxygenation and healing. When an ulcer is not healing as expected, vascular assessment may be appropriate.
If you have a diabetic foot wound that is not healing, shows signs of infection or is associated with numbness or circulation problems, a specialist assessment can help identify the next step.
